Hi there. I have a Pentium 4 2.8Ghz cpu processor with 1gb ram, 80 gig hard-drive as a primary hard-drive & a 300gig hard-drive as a secondary hard-drive. Anyway when i switch on my computer, everything starts up fine except my CPU TOWER led light stays constantly orange.It does not goes off or blink, previously it used to. I have got this PC for almost 2yrs now.I cannot figure out why the led light does not blink or flicker.Could any1 please help & tell me what could be wrong? I would really appreciate.Many thanks.Sashen
